HYDROCARBON-BURNER.

- ESPECIFICATION forming part of Letters Patent N 0. 463,629, dated November 24, 1891.

Application filed June 16, 1891.

To all whom it may concern.-

Be it known that I, WILLIAM R. J EAVONS, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hydrocarbon-burners of the class described in Letters Patent of the United States No. 438,348, dated October 14, 1890.

The object of this improvement is to prod uce more perfect combustion than has hitherto been obtained and to cheapen and simplify the construction of the parts. To these ends I arrange an air resisting, checking, or impeding device, partition, or plate in connection with the inner tube, and of such construction that while it allows a certain quantity or volume of airto pass directly through to feed and complete combustion above the same is yet close enough to so obstruct or impede the flow of air that a sufficient portion will be forced through the perforations of the inner tube to give the requisite aid to combustion between the two tubes.

Hitherto in burners of the variety of which this is a type a close diaphragm or its equivalent has been used in connection with the inner tube, whereby the air was entirely out off in its passage through the tube, except through the perforations in its side where it entered the combustion-chamber; but I have learned from actual experience that this was objectionable, because it left a dead place over this diaphragm at the bottom of the vessel, and thus detracted from the efficiency of the burner. I have overcome this objection and improved'combustion and the heating capacof gas or oil by allowing a limited quantity of. air to flow through into the space within the radius of the inner tube at its top, where it gives life to the dead space and produces flame and heat.

In the accompanying drawings, Figure 1 is a vertical section of a burner in which my improvement is shown in cross-section, and a Serial No. 396,448. (No model.)

perspective view of which in connection with the inner tube alone appears in Fig. 2.

A modification of the invention appears in Fig. 3, in which the check-plate or partition is depressed at the center instead of being raised, as in Fig. 1.

Fig. 4: shows still another modification, in which the said plate or partition is oval and has a single opening instead of several, as in the other figures.

Still other modifications might be suggested; but these are supposed to be sufficient to show the nature and scope of the invention.

A represents the burner-base, B the outer burner-tube,'and O, the inner burner-tube.

D is a device for checking, impeding, or obstructing the passage of air up through the inner tube, so as to force a portion of the air into the combustion-chamber through the perforations in the inner tube, otherwise if the tube were wholly open its entire length the chamber between the two tubes would be robbed of at least part of the air which the construction of the burner contemplates and requires. This device may have any one of the forms shown, or such other form as would operate with a like effect, the two purposes being kept in view of both forcing part of the inner air through the perforations in the inner tube and allowing a certain portion to pass directly through the device to feed combustion in the space immediately over it. In 85. any case, however, this device, plate, or partition does not act as a-defiector on the flame that issues from the combustion-chamber, but is confined to the inner tube to determine the distribution of air in the directions and for 0 the purposes just described.

The need of a device of this kind will be more clearly apparent when it is remembered that a blue flame beginning well down between th perforated walls shoots several inches above the walls or tubes, and it has been found that with the inner tube wholly closed at the top the flame is not as pure as desirable, for the reason that the admission of air to the combustion-chamber is limited at all points by the perforations, and in consequence a quantity of unconsumed or partially-consumed vapor is carried up with the flame above the fines. This vapor, though in.

a heated condition, failing to be supplied with the requisite amount of oxygen to burn and being directed against a cool cookingutensil, is apt to be so reduced in temperature that it will wholly escape combustion and pass off to vitiate and poison the surrounding atmosphere; hence the construction of the checking device as herein described by or through which air is fed to the flame above the combustion-chamber from Within, as Well as from without, and thus the nnconsumed vapors are unavoidably ignited and combustion is rendered not only complete, but the efficiency of the burner is correspondingly en hanced.

Having thus described my invention, What I claim as new, and desire to secure by Let-- ters Patent, is-

\Vitness my hand to the foregoing" speciti- 3o cation this 12th day of June, 1891.
